Team Associated RC18T Spur Gear Set 55T/57T/59T RC18-031 for tuning by 3Racing  [RC18-031]

RC18T spur gear tuning set

This 3-piece plastic spur gear kit offers 55, 57 and 59 tooth options to tune gearing on Team Associated RC18T electric cars. The selection gives straightforward steps to trade acceleration for top speed without swapping pinions, useful for changing track conditions or battery choices.

To fit, remove the gearbox cover, position the chosen spur on the gearbox shaft, check mesh with your pinion and secure using the original retaining parts. After installation check gear engagement under a light load and confirm chassis fastener torque to avoid play. Reuse the existing shim stack or washers to keep correct mesh spacing.

Kept as spares or for quick setup changes, these plastic spurs are intended for hobby RC electric drivetrains. Inspect gears regularly after aggressive runs and replace when tooth edges are rounded or damaged.
